Description

Technical Field

[0001] This utility model relates to the technical field of self-tapping screws with a plum blossom shape, specifically a self-tapping screw with a plum blossom shape. Background Technology

[0002] Torx screws, also known as internal Torx screws or star screws, are commonly found in automotive, motorcycle, and bicycle braking systems, hard drives, computer systems, and consumer electronics. Due to their design, Torx screws have a better head offset than Phillips head screws or slotted screws. Phillips head screws are designed to allow the screwdriver head to deflect to prevent over-tightening, while Torx screws are designed to prevent the screwdriver head from deflecting. This design shift stems from the widespread use of automatic torque control screwdrivers in factories. Torque control screwdrivers are designed to provide a stable, predetermined torque, rather than requiring the tool to slip out of the screw head after reaching a certain torque, risking damage to the screwdriver tip, screw head, or even the workpiece.

[0003] However, the strength of current Torx-shaped self-tapping screws is relatively low. When people tighten Torx-shaped self-tapping screws with a large force, the Torx-shaped self-tapping screws may bend or break, which greatly reduces the applicability of Torx-shaped self-tapping screws. Therefore, those skilled in the art have provided a Torx-shaped self-tapping screw to solve the problems mentioned in the background art. Utility Model Content

[0004] The purpose of this invention is to provide a plum blossom-shaped self-tapping screw to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A self-tapping screw with a star-shaped design includes a shank, a star-shaped head mounted on the outer surface of the shank, a screw tip mounted on the outer surface of the shank, reinforcing ribs arranged in a ring on the outer surface of the shank, and an anti-corrosion layer connected to the outer surface of the shank.

[0007] As a further improvement of this utility model: a flange is provided on the outside of the nail rod, and the flange is made of stainless steel.

[0008] As a further improvement of this utility model: a buffer pad is snapped onto the outer surface of the plum blossom nail head, and the outer surface of the buffer pad is connected to the flange.

[0009] As a further improvement of this utility model: the outer surface of the plum blossom nail head is provided with a slot, and the outer surface of the buffer pad is equipped with a locking block, and the slot and the locking block are adapted to each other.

[0010] As a further scheme of the utility model: the buffer pad is of rubber material, and the anticorrosive layer is of anticorrosive paint surface.

[0011] As a further scheme of the utility model: the outer surface of the plum-blossom-shaped head is provided with a plum-blossom-shaped groove, and the outer surface of the shank is connected with a self-tapping thread.

[0012] Compared with the prior art, the utility model has the beneficial effects that:

[0013] The plum-blossom-shaped self-tapping threaded screw, through the arrangement of the reinforcing rib and the anticorrosive layer, not only greatly increases the overall strength of the shank, but also enables the shank to have the anticorrosive feature, thereby greatly increasing the service life of the shank; the arrangement of the buffer pad, the clamping groove, the clamping block and the flange can increase the contact area of the screw and the surface of the connected member, thereby improving the stability and sealing property of the connection, and also can play a certain anti-loosening role; the arrangement of the plum-blossom-shaped groove facilitates the tightening or loosening operation by using a special plum-blossom-shaped screwdriver or wrench, and can provide better torque transmission and operation convenience.
